Specification of Letters Patent.

Patented Nov. 28, 1916.

Application filed October 2, 1916. Serial No. 123,257.

To all whom it may concern Be it known that I, WILLIAM C. HEDGCOC-K, acitizen of the United States, and resident of Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Emergency-Brake Beam Supports, of which the following isa specification.

My invention relates to railway car brakes and has particular referenceto a novel emergency supporting means. The construction here illustratedis an improvement on the construction of the patent to Elliott, No.1,147,793 dated July 27, 1915.

It has been found in practice that the excessive vibration of the trucksof the cars to which these devices are applied causes excessive wear.Particularly in this true where the horizontal bar which serves tounderlie the brake beams is supported by hangers in the form of plateshaving transverse apertures, the area of support being only that of thewidth or thickness of the material. It is found that the bar becameweakened by being cut vertically. As a means for obviating thisdifiiculty I have provided for a practically unlimited area of supportfor the bar by turning up or upsetting thelower end of the bar, the topor horizontal surface of the upset portion lying in the plane of thebottom of the aperture through the hanger. By this means a wide bearingarea'is provided.

The invention will be more readily understood by reference to theaccompanying drawings, wherein Figure 1 is a side elevation showing acar truck side frame in dotted lines, the brake beams in section and myimproved supporting device in elevation; Fig. 2 is a plan View showingthe relation of the bar to the brake beam; Fig. 3 is a sectional view onthe line 3-3 of Fig. 1;-Fig. 4 is a fragmentary elevation of a slightmodification, and Fig. 5 is a sectional View on the line 55 of Fig. 4.

Referring more particularly to the drawings, it will be seen that theside frame is indicated at 10, the sprin plank at 11 and the brake.beams at 12. cated near each end of the channel spring plank 11 aredepending hangers 18, the upper ends of which are hooked over theflanges of the channel and the lower ends of which are upset or bent ata right angle, as indicated at 14. An aperture 15 is provided in thehanger, the lower extremity of the opening being in a plane with the topsurface of the offset portion 1.4 of the hanger. A bar 15, which ispreferably of I beam construction, is passed longitudinally through theapertures 15 in the hangers and is retained in position by suitable keys16. By reason of the construction shown, it will be seen that a wideshelf is provided upon which the bar may rest, and that the wear due tovibration will be. reduced materially.

In Figs. 4 and 5 the modification which I have illustrated consists inincreasing the area by upsetting the end of the hanger 18, therebyproviding two shelves 19, 20, one at each side of thehanger, the topsurfaces of both of which shelves being as heretofore in the plane ofthe bottom of the opening,

which I have indicated at 21, through the hanger.

Obviously other modifications may be made than those illustrated and Ido not wish to be limited to the exact forms herein shown and described.

I claim: p

1. In a device of the class described, the combination of a hanger, ahorizontal bar engaging an aperture in said hanger, the lower end ofsaid hanger being bent angularly to provide an increased bearing areafor said horizontal bar, substantially as described.

2. In a device of the class described, the combination of a pair ofvertical hangers, a horizontal bar engaging an aperture in each hangerand a lateral shelf on the lower end a bar adapted to engage said hangerby a Signed at Chicago, Illinois, this 27th day longitudinal slidingmovement, and a shelf of September, 1916.

formed as a part of said hanger and adapted WILLIAM C. HEDGCOCK. tounderlie said bar and provide a relatively lVitnesses: 5 wide supportfor said bar, substantially as GEORGE A. PETERSON,

described. GEORGE S. CHILES.
